Air Force fired projectiles of some sort at alien craft and hit them directly, causing all of the craft fired upon to hit the ground.

I witnessed for the first time the most unbelievable thing that proves something I didn't believe in before I witnessed it occur. The United States Government scrambled jets to intercept groups of alien craft all day long as I sat and watched it from my living room window. I am in such disbelief, because like I said I was not a firm believer in life outside of our own planetary system. It is the truth, the craft I saw moved so quick, made no noise, but our craft being F-15 fighters I believe or something similar in nature, we able to use their weapons systems, perhaps modified systems, and shot them down...catching flame and landing in the mountain range of the Rocky Mountains. The craft, all 9 of them, fell from the sky when our weapons hit them, which indicated to me that in fact they were destroyed. Right now I am certain that because it did not make the news, that there is a top secret cover up, naturally the government wanting to keep this under wraps and I can understand the reasoning. The craft kept appearing, making me believe that we were not being successful in hitting them with our weapons systems. I saw trails, indicating something was fired from our craft towards theirs. Then I saw two craft together, indicating to me that in fact we were destroying their craft afterall, since they struck both craft together and they fell to the ground at a fast pace. The total number of planes of our aircraft varied throughout the day as they scrambled to attack them, but they arrived quickly and to my surprise given that our craft appear to be such lower in technology than theirs...but to my surprise again, simple systems of weaponry brought down what must have been intruders in our airspace and caught or detected by Space Command or Norad, or some other top secret detection facility...I'm convinced that we must have such things now that I am convinced that we've had bad visitors from outerspace. Their craft were triangular in shape, could move in any direction in an instant, but for some ! reason t hey weren't able to duck and weave whatever weapon it was that the United States Air Force was firing upon them, which was something unconventional you could tell by their streams that they left in the air...very different looking, almost as if to trace the location of the missiles from start to finish. I believe, knowing weapons systems very well from the Reagan era that are in use today, despite treaties, that satellites lit up the craft from the sky up high, and the missiles were guided directly to their targets without fail. I did see one alien craft seem to disappear in an instant, or it traveled from its location in an instant. All 9 craft that I saw were hit and fell to the ground behind some mountains. All scrambling jets ceased to fly once they were shot down, but it's not reported in the media and I haven't heard of anyone else seeing what I saw. So I do know it's being covered up in large scale. This is not the first sighting I've had with triangular craft. A group of about 7 or so flew directly over my condo one night, had zero noise in propulsion, flew very slow, and were lit up from beneath for all to witness, didn't seem to be afraid of showing themselves off. This event was in Lakewood, CO at the time probably 2 years ago.
